Hi, No you are not alone, as i can relate to what you have said.
Now,i do my best to manage my impulisive behaviour, i do have B.P.D and other issues to manage as well, but its not easy. At the moment i have become stuck in life again , i have no friends, i rarely go out by myself.
I do see a therapist and i am glad i have found this site,as i can only realy talk to my therapist and i check out this site every now then.
As far as making decisions, i try to set goals for myself, but most often, i usualy talk myself out of what ever my intentions were.
And, yes sometimes, i feel like saying.... Hello , is anybody out there. Wish you the very best.
